Q1: Where are your microbes produced?
Ans:  Singapore.


Q2: Can you tell us more about your “no water discharge” biodigester that does not require water drainage installation?
Ans:  Aerobic digestion requires no additional water… no water discharge, so no additional piping. Hence no compliance issues with PUB sewage system.

Ans:  During the process when the microbes degrade the food waste, water from the food waste are emitted and released to the environment through our digester. All this happens at low temperature below 40*C.

Ans:  Analogy when you are doing exercise, water is emitted as sweat from you skin with your body temperature above 30+ *C.


Q3: How to we handle the fertiliser by-product after food waste composting?
2 types of customers here:
Ans: Some customers want to keep the fertiliser for their own planting use, example of system in Sentosa Golf Club.

Ans: Some customers that don’t need the fertiliser, we help them dispose it during our routine servicing, example those systems we deployed in JTC’s food hub.


Q4: What happen if non-food waste items are disposed in the food waste digester ?
Ans: If you recall my previous slide on aerobic digestion process, there is an agitator that rotates slowing to mix the food waste and microbes to degrade the food waste. If non-food waste items (eg plastics bags, paper, or large bones) are inside, the microbes will not degrade them. It can be sieve out from the fertiliser and you could do a post segregation.

Q5: Are we able to track usage of user (individual) Data (information) for mandatory monthly food waste report?
Ans:  The system is RFID enabled, where we can collect data from user(s) and to facilitate submission of monthly food waste report.


Q6: How frequent do we need to top up microbes?
Ans:  During initial installation of the system, we load 50% microbes. Say for 1 ton of food waste, we add 500kg of microbes.

Ans:  Over 24 hours of composting, the 1 ton food waste are converted and reduced to 100 kg (10%) of fertiliser. The microbes will continue to work, and you can continue to load food waste into the system.

Ans: During routine servicing, (2-4 weeks depending on capacity utilization and dampness of food waste loaded), fertilizer are harvested, and we refill about 20% microbes (200kg).


Q7: The digester seems huge. is there a more compact model where space is a problem?
Ans:  Our digester ranges from the retail capacities at 2-5kg, commercial capacities at 20-100kg and industrial capacities at 300-2000kg. Depending on how much food waste is produce we will recommend it after doing a food waste audit.
Do contact us for a site survey to get the digester that is fitting to your facilities’ needs.


Q8: How do you manage the smell from the waste digester? is the digester installed in any of the healthcare environment?
Ans:  Our proprietary microbes have the capability to break down the food waste after 24 hours and eliminating the rotten food particulates in the process. Also, our design of the hardware seals all the microbites and food waste in a concealed tank, keeping any form of odour internally while the microbites acts on the food waste.
Yes. Our digester is installed in Khoo Tech Puat Hospital.


Q9: will there be a need to test the fertilizer before use? Since each batch of food waste disposed may differ.
Ans:  The nutrients generated by the food waste in different batches will differ due to different mix of food input. If the compost is used solely for landscaping purpose, there is no need for any tests to be done. Generally, our compost will need further treatment for additional of various nutrients to balance it out for farming/agricultural use.


Q10: Is the food waste digester able to accept all kinds of segregated food waste including post cooked food with oil?
Ans:  Our proprietary microbes can accept food waste that is has high water content like fruits and vegetables. Post cook food with oil can be treated but not in large amount that is close to the load capacity. With large amount of oil, there is a possibility that the microbites may not survive.
